Platinum drops in and eats out : Platinum nanoparticles penetrate from the surface of the zeolite into its bulk, creating hexagonal mesopores of about the same width as the platinum particles (see micrograph). It is as if the platinum particles tunnel into the crystal. The mesopores are formed along particular directions in the zeolite crystal, and their walls consisted of specific zeolite crystal faces.
